. To all 'whom 'it may concern.'

Be it known that I, PHILIPP Pennes, vicel president, a subject of the Emperor of Austua-Hungary, and a resident of Vienna, in

the Empire of AustriaHungary (Whose post-office addressis'Vienna, I, Stubenring 12,) have invented a Crude-Oil Preheater, of which the following is a specification.

The utilization of the heat contained in the distillates, for the purpose of preheating crude oil has been carried out heretofore (see for example the Austrian Letters `patent No. 6245) in such manner, that the distillates, the heat whereof is to be utilized, are conducted into 'distributers, whichare disposed outside of the pre-heating ves.

sel. This arrangement is disadvantageous.l

It causes considerable loss of heat, since the distributing pipes placed outside of the pre-heater, together with their numerous fittings, fianges and pipe-connections, constitute a radiating surface which is quite extensive. If, in time, the necessityr of renewing the pipes arises then it'becomes necessary to remove the distributers or ma iolds and to remove pipes from their wall, -and such work of dismounting 'and also of replacing such pipes, produces considerable difliculties, and besides derangements in the working of the plant; it causes delays in boiling and overfiow of the contents of the pre-heater. These drawbacks are obviated by the present invention, by arranging the distributers or manifolds in the interior of the pre-heater. Thereby all losses due to radiation `are avoided, or 4in othei,- words, substantially all of the heat' is utilized to heat the crude foil. The exchangeability of the pipes is much easier than for example. with the pre-heatera-ccording to the lAustrian Letters Patent No. 6245. The pipes may be arranged at will in the lowest part of the casing of tliepreheater, as near as possible to the casing, whereby 'thellowest contents of the preheater vessel becomes heated. 'The bottom of the pre-heater-vessel remains absolutelv free and may be utilized for fitting thereto all the necessary fittings as inletand outlet-connections, thermometers, manometers and also -a man-ho le; the arrangement of' such fittings on the said part has met unt-il now with difficulties. The arrangement vmay be executed in. such manner that the pipes may expand und consible to the verticzl center line of tract. under the inuence of heat Without obstruction, whereby the pipe' connections are not submitted to any stress and whereby the packings are secured from injuries causedY otherwise by expansions of the pipv450 ing.

With the form of the invention, as illustrnted in the drawings, the manifold or y distributer, that is the inlet-distributer el, is fixed to the pre-heater `vessel', whereas the other distributers c2 c are freely 'ir/lovable whereby the pipes may expand fand contract freely under the influence ofheat and whereby leakagesat the joints. by expensions of the pipes are avoidedr-The inlet h or h, respectively is arranged laterally, whereby the same remains uninlongitudinal dil'eftion ns caused by expansion, the inlet remaining thereby unchangeable. in its position.

By the use of pipes provided with ribs or fluenced by the play of the casing, in the 10 of wave-like bent pipes as inner pipes the m5 heating surface is increased; by suitably adjusting such ribs upon the pipes 0bstacles can be offered to the passing liquid. The ribs may be fixed to the may be screwed to smooth pi pipes or they n Hai-ving described the nature off rnyminvention, 'what I claim is: l.
